Professional Applications & Engineering Value
This 6-32 UNC set screw is engineered to address common challenges in industrial settings, such as component slippage and vibration-induced loosening. The cup point tip design concentrates pressure to create a firm grip on shafts and collars, while the cadmium-plated alloy steel construction offers excellent resistance to corrosion and mechanical stress. With a Class 3A thread fit and coarse UNC thread spacing, it ensures quick, accurate installation in assemblies requiring high clamping force, from automotive systems to precision machinery. This headless set screw with a hex drive is ideal for space-constrained applications, providing reliable performance that minimizes downtime and maintenance costs.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 3A thread fit for tight tolerances and UNC coarse threads (6-32 size) with a diameter of 0.138". It meets MS51963-21 specifications for quality assurance and is manufactured from cadmium-plated alloy steel, complying with industry regulations for durability and performance in mechanical fastening applications.
